The RHEL3 driver disks are now available here.

There are separate driver disk images for each of "athlon", "i386", "i586", and "i686". Choose the one that best matches your CPU, and if it fails to load correctly, try a different one.

These were built under RedHat9, not EL3, but I think they should work regardless of minor differences in the tool chain. Let me know how you make out with them.

To use them, you'll need a working Linux system, from where you can do something like this (below) to create an actual floppy diskette:
Code:

---

   zcat  dd.img-i686.gz  >  /dev/fd0h1440

---

Cheers
